Abstract
Description
本發明係有關於一種適用於鐵道車輛、汽車、飛機、船舶及建築物之窗玻璃的調光窗。 The present invention relates to a dimming window for window glass for railway vehicles, automobiles, airplanes, ships, and buildings.
鐵道車輛用之窗玻璃為了提高隔音性、隔熱性及安全性，一般是使用多層玻璃(參閱專利文獻1等)。而該多層玻璃係室外側玻璃板與室內側玻璃板隔著間隔件而隔開設置，且周緣部係由密封材料所密封而構成。 In order to improve sound insulation, heat insulation, and safety, window glass for railway vehicles is generally used as a multi-layer glass (see Patent Document 1, etc.). On the other hand, the multi-layer glass outdoor side glass plate and the indoor side glass plate are spaced apart from each other via a spacer, and the peripheral portion is sealed by a sealing material.
又，專利文獻1之多層玻璃之室外側玻璃板，為了抑制來自外部之光及熱的入侵，而具備有自我調光薄膜。該自我調光薄膜係利用濺鍍法而成膜於室外側玻璃板兩面中之向著室內側玻璃板的面上。該自我調光薄膜在外部光線之強度低時，可使可見光穿透率為70~90%，而外部光線之強度高時，則可使可見光穿透率為50~70%。但是，使用了自我調光薄膜時，因為穿透率會因應外部光線之強度而變化，故乘客難以任意調整穿透率。 Further, the outdoor side glass plate of the multilayer glass of Patent Document 1 is provided with a self-dimming film in order to suppress invasion of light and heat from the outside. The self-dimming film is formed on the surface of the outdoor side glass plate on both sides of the outdoor side glass plate by a sputtering method. The self-dimming film can have a visible light transmittance of 70 to 90% when the intensity of the external light is low, and a visible light transmittance of 50 to 70% when the intensity of the external light is high. However, when a self-dimming film is used, since the transmittance varies depending on the intensity of external light, it is difficult for the passenger to arbitrarily adjust the transmittance.
又，除了前述自我調光薄膜以外，還考慮著將藉 由施加電壓使光穿透率變化之調光片例如懸浮粒子裝置(以下，稱「SPD(Suspended Particle Device)」)應用於調光窗。該SPD具有於施加電壓時變成透明，於非施加電壓時變成不透明(即變暗)之特性。 Moreover, in addition to the aforementioned self-dimming film, it is also considered to be borrowed A dimming plate such as a suspended particle device (hereinafter referred to as "SPD (Suspended Particle Device)) which changes the light transmittance by applying a voltage is applied to the dimming window. The SPD has a property of becoming transparent when a voltage is applied and becoming opaque (i.e., darkening) when a voltage is not applied.
然而，因為前述SPD一旦施加的電壓被切斷的話，窗即會變成不透明，故一旦發生停電等事故，即會有室內變暗之虞。 However, since the window is opaque once the applied voltage is cut off, the indoor darkening may occur if an accident such as a power outage occurs.
對此，專利文獻2中則揭示有一調光板材，該調光板材係於施加電壓時會變成不透明，而於非施加電壓時會變成透明。且該調光板材係藉由將由反向模式型之液晶與硬化物形成之液晶調光材料封入2片附透明電極之透明板材之間而構成。依據該調光板材，若施加地電壓被切斷時即會變成透明，故可於停電時等之事故發生時，防止室內變暗。 In this regard, Patent Document 2 discloses a light-adjusting sheet which becomes opaque when a voltage is applied and becomes transparent when a voltage is not applied. The dimming plate is formed by enclosing a liquid crystal light-adjusting material formed of a reverse mode liquid crystal and a cured material between two transparent plates with transparent electrodes. According to the light-adjusting sheet, when the applied ground voltage is cut off, it becomes transparent, so that the indoor darkening can be prevented when an accident such as a power failure occurs.
專利文獻1：日本特開2004-175622號公報 Patent Document 1: Japanese Laid-Open Patent Publication No. 2004-175622
專利文獻2：日本專利第3890841號公報 Patent Document 2: Japanese Patent No. 3890841
本案發明人等經檢討後即明白，專利文獻2所揭示之調光板材因僅具有擴散外部光線之機能，即僅具有使外部光線朦朧之機能，故難以減低外部光線之眩光。 As a result of reviewing, the inventors of the present invention have understood that the dimming plate disclosed in Patent Document 2 has a function of diffusing external light, that is, it has only a function of causing external light to smash, so that it is difficult to reduce glare of external light.
並且，單獨將前述調光板材作為調光窗應用時，調光板材因對風壓等之外力弱，故有難以單獨應用之問題。 Further, when the dimming plate is used alone as a dimming window, the dimming plate has a weak external force such as wind pressure, so that it is difficult to apply it alone.
本發明係有鑑於前述情事而作成者，目的在於提供一種具有防眩機能及已提升對外力之抗衡力量之調光板材的調光窗。 The present invention has been made in view of the foregoing, and it is an object of the invention to provide a dimming window having an anti-glare function and a dimming sheet having an opposing force against external force.
本發明之一態樣為了達成前述目的而提供一種調光窗，其特徵在於具有：多層玻璃，其至少具有配置於室外側之室外側玻璃板與配置於室內側之室內側玻璃板，且室外側玻璃板與室內側玻璃板係隔著間隔件及密封材料而隔開設置，以使室外側玻璃板與室內側玻璃板之間形成有中空層；及調光板材，其係於2片附透明電極之透明板材之間封入液晶調光材料而成，且於施加電壓時會變成不透明，於非施加電壓時會變成透明，該液晶調光材料係由反向模式型之液晶與硬化物所形成；並且，前述室外側玻璃板及前述室內側玻璃板中之其中一玻璃板之可見光穿透率在70%以下；前述調光板材係安裝於前述室外側玻璃板與前述室內側玻璃板之對向面中之一對向面上而成者。 According to one aspect of the present invention, in order to achieve the above object, a dimming window is provided, comprising: a multi-layer glass having at least an outdoor side glass plate disposed on an outdoor side and an indoor side glass plate disposed on an indoor side, and a chamber The outer glass plate and the indoor side glass plate are spaced apart from each other via a spacer and a sealing material, so that a hollow layer is formed between the outdoor side glass plate and the indoor side glass plate; and the dimming plate is attached to the two pieces. The transparent plate of the transparent electrode is sealed with a liquid crystal light-adjusting material, and becomes opaque when a voltage is applied, and becomes transparent when a voltage is not applied. The liquid crystal light-adjusting material is a liquid crystal and a hardened material of a reverse mode type. And forming, wherein one of the outdoor side glass plate and the indoor side glass plate has a visible light transmittance of 70% or less; and the dimming plate is attached to the outdoor side glass plate and the indoor side glass plate; One of the opposite faces is opposite to the face.
因此，依據本發明之一態樣，藉由搭配使用Tv在70%以下之玻璃板與調光材料，於外部光線進入室內前光的強度會減弱，從而作為調光窗可發揮充分之防眩效果。並且，調光板材因為由多層玻璃所保護，故可提升對外力之抗衡力量。 Therefore, according to one aspect of the present invention, by using a glass plate and a light-adjusting material having a Tv of 70% or less, the intensity of the external light entering the room is weakened when the external light enters the room, thereby providing sufficient anti-glare as a dimming window. effect. Moreover, since the dimming plate is protected by the multi-layer glass, it can enhance the counter force of the external force.
Tv在70%以下之玻璃板可為單板之玻璃板，亦可 為層合玻璃。Tv在70%以下之單板玻璃板，可藉由於製造玻璃板時，將近紅外線區域之光吸收劑添加於玻璃材料中，或是將近紅外線區域之光吸收材料塗布於玻璃板來製造。Tv在70%以下之層合玻璃，可藉由使用於中間膜之材料中僅添加了近紅外線區域之光吸收劑的近紅外線型之中間膜來製造。 A glass plate with a Tv of 70% or less may be a single-plate glass plate, or For laminating glass. A single-plate glass plate having a Tv of 70% or less can be produced by adding a light absorber in a near-infrared region to a glass material or a light-absorbing material in a near-infrared region to a glass plate when a glass plate is produced. A laminated glass having a Tv of 70% or less can be produced by using an interlayer film of a near-infrared type in which only a light absorber of a near-infrared region is added to a material of an interlayer film.
本發明調光窗之一態樣係以安裝於前述多層玻璃之室內側玻璃板之中空層側面，即室內側玻璃板之與室外側玻璃板之對向面上為佳。 One aspect of the dimming window of the present invention is preferably mounted on the side of the hollow layer of the indoor side glass plate of the multi-layer glass, that is, the opposite side of the indoor side glass plate and the outdoor side glass plate.
室外側玻璃板及室內外側玻璃板雖會因風壓而發生撓曲，但室內側玻璃板因風壓所致之影響少。依據本發明之一態樣，因將調光板材安裝於不會發生撓曲之室內側玻璃板上，故可防止起因於調光板材撓曲所致液晶調光材料之劣化。 Although the outdoor side glass plate and the indoor and outdoor glass plates are deflected by the wind pressure, the indoor side glass plate has little influence due to the wind pressure. According to an aspect of the present invention, since the dimming plate is attached to the indoor side glass plate which does not flex, the deterioration of the liquid crystal light adjusting material due to the deflection of the dimming plate can be prevented.
本發明之一態樣為：前述室外側玻璃板及前述室內側玻璃板中之至少一玻璃板宜具有紫外線遮蔽機能。藉此，可減低液晶調光材料之紫外線所致之劣化。 According to an aspect of the invention, at least one of the outdoor side glass plate and the indoor side glass plate preferably has an ultraviolet shielding function. Thereby, the deterioration caused by the ultraviolet rays of the liquid crystal light-adjusting material can be reduced.
依據本發明之一態樣，於其中之一玻璃板為單板的情況時，在製造玻璃板時只要使玻璃材料中添加紫外線遮蔽材料即可，並且亦可將紫外線遮蔽膜成膜於玻璃板表面使其具有紫外線遮蔽機能。又，於其中之一玻璃板為層合玻璃的情況時，亦可使中間膜之材料中添加紫外線吸收材料使其具有紫外線遮蔽機能。 According to an aspect of the present invention, in the case where one of the glass sheets is a single sheet, it is only necessary to add an ultraviolet shielding material to the glass material when manufacturing the glass sheet, and the ultraviolet shielding film may be formed on the glass sheet. The surface gives it an ultraviolet shielding function. Further, when one of the glass sheets is a laminated glass, an ultraviolet absorbing material may be added to the material of the intermediate film to have an ultraviolet shielding function.
本發明之一態樣為：前述室外側玻璃板及前述室 內側玻璃板中之至少一玻璃板宜為吸熱玻璃、熱反射玻璃或是隔熱玻璃。只要使用該等玻璃，則可抑制封入有液晶調光材料之多層玻璃之空氣層內之溫度上昇。而其結果可減低液晶調光材料因熱而劣化。 One aspect of the present invention is: the outdoor side glass plate and the aforementioned chamber At least one of the inner glass sheets is preferably an endothermic glass, a heat reflective glass or an insulating glass. When these glasses are used, the temperature rise in the air layer of the multilayer glass in which the liquid crystal light control material is sealed can be suppressed. As a result, the liquid crystal dimming material can be degraded due to heat.
依據本發明之一態樣，於其中之一玻璃板為單板時，可將熱反射膜成膜於玻璃板之表面上，或是於玻璃板之表面上黏貼熱反射薄膜而製成為熱反射玻璃。又，於其中之一玻璃板為層合玻璃時，則可使中間膜之材料中添加紅外線吸收劑而製成為吸熱玻璃。 According to an aspect of the present invention, when one of the glass plates is a single plate, the heat reflective film may be formed on the surface of the glass plate, or the heat reflective film may be adhered to the surface of the glass plate to be thermally reflected. glass. Further, when one of the glass sheets is a laminated glass, an infrared ray absorbing agent may be added to the material of the intermediate film to form a heat absorbing glass.
如以上所說明的，依據本發明，可藉由具有防眩機能的同時減低混濁感，來提供一種可提升外觀，又具有已提升對外力之抗衡力量之調光板材的調光窗。 As described above, according to the present invention, it is possible to provide a dimming window which can improve the appearance and has a dimming plate which has improved the external force by the anti-glare function while reducing the turbidity.

[第1實施形態之調光窗10之結構] [Structure of Dimming Window 10 of First Embodiment]
調光窗10係由多層玻璃12與調光板材(商品名「Transmart」：旭硝子股份有限公司製)14所構成。 The dimming window 10 is composed of a multi-layer glass 12 and a dimming plate (trade name "Transmart": manufactured by Asahi Glass Co., Ltd.).
〔多層玻璃12〕 [Multilayer glass 12]
多層玻璃12具有矩形之室外側玻璃板16、矩形之室內側玻璃板18、框狀之間隔件20以及密封材料22及26。室外側玻璃板16及室內側玻璃板18，該等之表面積相等，且係隔著間隔件20而隔開設置。於第1實施形態中，密封材料係使用一次密封材料22及二次密封材料26。向著室外側玻璃板16及室內側玻璃板18之間隔件20的各側面是利用丁基橡膠(一次密封材料)22而與室外側玻璃板16及室內側玻璃板18接合。藉此，於室外側玻璃板16及室內側玻璃板18之間會形成有中空層24。然後，於間隔件20之外周部上塗布有聚矽氧密封材料(二次密封材料)26。藉此，而構成多層玻璃12。密封材料並未侷限於前述形態，亦可令與室外側玻璃板16及室內側玻璃板18接合的一次密封材料22及塗布間隔件20之外周部的2次密封材料26為同一材料。並且，於二次密封材料26之外周亦可具有用來保護二次密封材料26之別的密封材料。 The multilayer glass 12 has a rectangular outdoor side glass plate 16, a rectangular indoor side glass plate 18, a frame-shaped spacer 20, and sealing materials 22 and 26. The outdoor side glass plate 16 and the indoor side glass plate 18 have the same surface area and are spaced apart from each other via the spacer 20. In the first embodiment, the primary sealing material 22 and the secondary sealing material 26 are used as the sealing material. Each of the side faces of the spacer 20 facing the outdoor side glass plate 16 and the indoor side glass plate 18 is joined to the outdoor side glass plate 16 and the indoor side glass plate 18 by butyl rubber (primary sealing material) 22. Thereby, the hollow layer 24 is formed between the outdoor side glass plate 16 and the indoor side glass plate 18. Then, a polysilicon sealant (secondary seal material) 26 is applied to the outer peripheral portion of the spacer 20. Thereby, the multilayer glass 12 is comprised. The sealing material is not limited to the above-described embodiment, and the primary sealing material 22 joined to the outdoor side glass plate 16 and the indoor side glass plate 18 and the secondary sealing material 26 on the outer peripheral portion of the coating spacer 20 may be made of the same material. Further, a sealing material for protecting the secondary sealing material 26 may be provided on the outer periphery of the secondary sealing material 26.
又，間隔件20係由中空的管子(例如縱截面形狀為約略矩形之中空的四方形管)所構成，並利用填充於其內部之乾燥劑28使中空層24之氣體乾燥。另外，符號30係為了使乾燥劑28露出於中空層24而形成之間隔件20的開口部，透過該開口部並利用填充於間隔件20之空間部的乾燥劑28來維持中空層24之乾燥狀態，而可防止多層玻璃冷凝。 Further, the spacer 20 is composed of a hollow tube (for example, a hollow square tube having a longitudinal cross-sectional shape of approximately rectangular shape), and the gas of the hollow layer 24 is dried by a desiccant 28 filled therein. Further, reference numeral 30 is an opening of the spacer 20 formed to expose the desiccant 28 to the hollow layer 24, and the drying portion 28 filled in the space portion of the spacer 20 is passed through the opening to maintain the drying of the hollow layer 24. State, which prevents condensation of multiple layers of glass.
〈室外側玻璃板16及室內側玻璃板18〉 <Outdoor side glass plate 16 and indoor side glass plate 18>
室外側玻璃板16及室內側玻璃板18，係室外側玻璃板16及室內側玻璃板18中，至少其中一玻璃板之可見光穿透率在70%以下。另外，「可見光穿透率」係依照JIS R3106(1998)所算出之值(JIS：日本工業標準規格)。 The outdoor side glass plate 16 and the indoor side glass plate 18 are the outdoor side glass plate 16 and the indoor side glass plate 18, and at least one of the glass plates has a visible light transmittance of 70% or less. In addition, the "visible light transmittance" is a value calculated according to JIS R3106 (1998) (JIS: Japanese Industrial Standard Specification).
前述其中一玻璃板為單板的情況時，在製造玻璃板時，可藉由將近紅外線區域之光吸收劑添加於玻璃材料中而製得可見光穿透率在70%以下之玻璃板。又，前述其中一玻璃板為層合玻璃的情況時，則可藉由使用於中間膜之材料中僅添加了近紅外線區域之光吸收劑的近紅外線吸收型之中間膜，而製得可見光穿透率在70%以下之玻璃板。 In the case where one of the glass sheets is a single sheet, in the case of producing a glass sheet, a glass plate having a visible light transmittance of 70% or less can be obtained by adding a light absorber in a near-infrared region to the glass material. Moreover, when one of the glass sheets is a laminated glass, the visible light can be obtained by using an intermediate film of a near-infrared absorption type of a light absorber in the near-infrared region. A glass plate having a transmittance of 70% or less.
於圖1中，室外側玻璃板16及室內側玻璃板18係顯示為單板之玻璃板。於本發明之實施形態中，室外側玻璃板16及室內側玻璃板18可為單板之玻璃板，亦可為層合玻璃，又亦可為多層玻璃。 In FIG. 1, the outdoor side glass plate 16 and the indoor side glass plate 18 are shown as a single plate glass plate. In the embodiment of the present invention, the outdoor side glass plate 16 and the indoor side glass plate 18 may be a single plate glass plate, or may be a laminated glass or a multiple layer glass.
作為單板之玻璃板，可列舉未施有強化處理之通常的玻璃板、經化學強化法強化之化學強化玻璃板，或是業經風冷強化之風冷強化玻璃板等。 Examples of the glass plate of the veneer include a normal glass plate to which no tempering treatment is applied, a chemically strengthened glass plate reinforced by a chemical strengthening method, or an air-cooled tempered glass plate which is reinforced by air cooling.
單板之玻璃板的厚度，可按照強化處理之有無及所使用之場所而適當地設計。舉例來說，使用了化學強化玻璃板作為室外側玻璃板16時之玻璃板的厚度，宜為3.0~4.0mm。藉此，使調光窗能製得輕量。又，使用了化學強化玻璃板作為室內側玻璃板18時之玻璃板的厚度，為了抑制玻璃板18之翹曲宜為2.0~3.0mm。 The thickness of the glass plate of the veneer can be appropriately designed according to the presence or absence of the strengthening treatment and the place where it is used. For example, when the chemically strengthened glass plate is used as the outdoor side glass plate 16, the thickness of the glass plate is preferably 3.0 to 4.0 mm. Thereby, the dimming window can be made lightweight. Moreover, the thickness of the glass plate when the chemically strengthened glass plate is used as the indoor side glass plate 18 is preferably 2.0 to 3.0 mm in order to suppress the warpage of the glass plate 18.
層合玻璃係由前述之單板玻璃板與中間膜所構成。作為中間膜可使用聚乙烯醇縮丁醛之中間膜(PVB(Polyvinyl butylal)系中間膜)，或是乙烯-乙酸乙烯酯共聚物之中間膜(EVA(Ethylene-Vinyl Acetate)系中間膜)。 The laminated glass is composed of the aforementioned single-plate glass plate and an intermediate film.

[第1實施形態之調光窗10之特徵] [Features of the dimming window 10 of the first embodiment]
第1實施形態之調光窗10之特徵在於：於由室外側玻璃板16及室內側玻璃板18構成之多層玻璃12的中空層24中封入有調光板材14。又，第1實施形態之調光窗10之特徵在於：將室外側玻璃板16及室內側玻璃板18中之其中一玻璃板之可見光穿透率設在70%以下。 The light control window 10 of the first embodiment is characterized in that a light-adjusting sheet material 14 is sealed in the hollow layer 24 of the multilayer glass 12 composed of the outdoor side glass plate 16 and the indoor side glass plate 18. Further, the dimming window 10 of the first embodiment is characterized in that the visible light transmittance of one of the outdoor side glass plate 16 and the indoor side glass plate 18 is set to 70% or less.
依據該第1實施形態之調光窗10，藉由可見光穿透率在70%以下之玻璃板及調光板材14，可使進入室內之外部光線之透射量減少，使外部光線之擴散而可獲得良好的防眩效果。並且，因為調光板材14由多層玻璃12所保護，故可減低因外力所致之調光板材14之劣化。 According to the dimming window 10 of the first embodiment, the glass plate and the light-adjusting plate 14 having a visible light transmittance of 70% or less can reduce the amount of external light entering the room and diffuse external light.

第1實施形態之調光窗10之較佳形態，其特徵在於：將調光板材14安裝於室內側玻璃板18上，特別是將調光板材14安裝於室內側玻璃板18之多層玻璃12之中空層24側的面18A上。室外側玻璃板16雖然會因風壓而撓曲，但室內側玻璃板18因風壓所致之撓曲小。因此，藉由將調光板材14安裝於難發生撓曲之室內側玻璃板18上，可防止起因於調光板材14之撓曲所導致之液晶32的劣化。 A preferred embodiment of the light control window 10 of the first embodiment is characterized in that the light control plate member 14 is attached to the indoor side glass plate 18, and in particular, the light control plate member 14 is attached to the multi-layer glass 12 of the indoor side glass plate 18. On the surface 18A on the side of the hollow layer 24. Although the outdoor side glass plate 16 is deflected by the wind pressure, the indoor side glass plate 18 has a small deflection due to the wind pressure. Therefore, by attaching the light-adjusting sheet material 14 to the indoor side glass plate 18 which is hard to be deflected, deterioration of the liquid crystal 32 due to deflection of the light-adjusting sheet material 14 can be prevented.

圖3係於一片室內側玻璃板18上黏貼有多個調光板材14之調光窗10之變形例。因調光板材14對室內側玻璃板18之黏貼形態有多種形態，故只要按照調光板材14及室內側玻璃板18之尺寸適當地作選擇即可。 3 is a modification of the dimming window 10 in which a plurality of light-adjusting sheets 14 are adhered to one indoor side glass plate 18. Since the bonding sheet 14 has various forms of adhesion to the indoor side glass plate 18, it is only necessary to appropriately select the size of the dimming plate 14 and the indoor side glass plate 18.
圖3(A)係顯示使6片調光板材14排列並黏貼於室內側玻璃板18整面上之調光窗10之變形例的說明圖。因使用多個調光板材14，故可隨意設定進行調光之場所。因此，可提升設計性，並可藉由將各個調光板材14細分化來提示 文字資訊。 Fig. 3(A) is an explanatory view showing a modification of the dimming window 10 in which six sheets of the light-adjusting sheet material 14 are arranged and adhered to the entire surface of the indoor side glass sheet 18.

By arranging the dimming sheet 14 as described, only a portion of the window has a dimming function, and the necessary and minimal dimming sheet 14 can be used to achieve the covering function.
[第2實施形態之調光窗40之構造及特徵] [Structure and Characteristics of Dimming Window 40 of Second Embodiment]
第2實施形態之調光窗40係由多層玻璃12、調光板材14及紫外線遮蔽層42所構成。 The light control window 40 of the second embodiment is composed of a multilayer glass 12, a light control plate member 14, and an ultraviolet shielding layer 42.
圖4係第2實施形態之調光窗40之主部縱截面圖，而關於與圖1所示之調光窗10相同之構件則附上相同之符號並省略其說明。 4 is a longitudinal cross-sectional view of the main portion of the dimming window 40 of the second embodiment, and the same members as those of the dimming window 10 shown in FIG. 1 are denoted by the same reference numerals, and their description will be omitted.
調光窗40因於室外側玻璃板16具有紫外線遮蔽層42，故可減低調光板材14之液晶32因紫外線而劣化的情形。紫外線遮蔽層42亦可分別成膜於室外側玻璃板16之外表面及室內側玻璃板18之外表面。而從藉由紫外線遮蔽層42來防止劣化之觀點來看，以設置於多層玻璃12之中空層24側上為佳。即，宜設置於室外側玻璃板16及室內側玻璃板18之對向面16A及18A中之至少一面上，且以設置於室外側玻璃板之對向面18A上尤佳。 In the dimming window 40, since the outdoor side glass plate 16 has the ultraviolet shielding layer 42, the liquid crystal 32 of the light control plate 14 can be degraded by ultraviolet rays. The ultraviolet shielding layer 42 may also be formed on the outer surface of the outdoor side glass plate 16 and the outer surface of the indoor side glass plate 18, respectively. On the other hand, from the viewpoint of preventing deterioration by the ultraviolet shielding layer 42, it is preferable to provide it on the side of the hollow layer 24 of the multilayer glass 12. That is, it is preferably provided on at least one of the opposing faces 16A and 18A of the outdoor side glass plate 16 and the indoor side glass plate 18, and is preferably provided on the opposing surface 18A provided on the outdoor side glass plate.
紫外線遮蔽層42可使用例如含有有機或無機之紫外線吸收劑的溶膠凝膠膜。作為有機之紫外線吸收劑可列舉二苯基酮類、三類、苯并三唑類、氰基丙烯酸酯類、甲亞胺類、吲哚類、柳酸酯類及蒽類等。而作為無機之紫 外線吸收劑則可列舉氧化鋅之微粒子等。溶膠凝膠膜可使用水解性矽化合物。並且，作為紫外線遮蔽層42亦可使用具有抗紫外線機能之薄膜(Scotchtint(TM)NANO80CP：3M公司製)。 As the ultraviolet shielding layer 42, for example, a sol-gel film containing an organic or inorganic ultraviolet absorber can be used. Examples of the organic ultraviolet absorber include diphenyl ketones and three Classes, benzotriazoles, cyanoacrylates, imines, anthraquinones, salicylates, and anthraquinones. Examples of the inorganic ultraviolet absorber include fine particles of zinc oxide. A hydrolyzable hydrazine compound can be used for the sol-gel film. Further, as the ultraviolet shielding layer 42, a film having anti-UV function (Scotchtint (TM) NANO80CP: manufactured by 3M) can also be used.
圖4之調光窗40，係於室外側玻璃板16之對向面16A上成膜有紫外線遮蔽層42。藉此，調光窗40會具有紫外線遮蔽機能。 The dimming window 40 of FIG. 4 is formed with an ultraviolet shielding layer 42 formed on the opposite surface 16A of the outdoor side glass plate 16. Thereby, the dimming window 40 has an ultraviolet shielding function.
[第3實施形態之調光窗50之結構及特徵] [Structure and Features of Dimming Window 50 of Third Embodiment]
第3實施形態之調光窗50係由多層玻璃12及調光板材14所構成，且多層玻璃中至少一玻璃板為層合玻璃。 The light control window 50 of the third embodiment is composed of a multilayer glass 12 and a light-adjusting sheet 14, and at least one of the plurality of glass sheets is a laminated glass.
圖5係第3實施形態之調光窗50之主部縱截面圖，而關於與圖1所示之調光窗10相同之構件則附上同一符號並省略其說明。 5 is a longitudinal cross-sectional view of the main portion of the light-adjusting window 50 of the third embodiment, and the same members as those of the dimming window 10 shown in FIG. 1 are denoted by the same reference numerals, and their description will be omitted.
圖5之調光窗50係使用層合玻璃52作為室外側玻璃板。層合玻璃52係眾所周知之層合玻璃，其於2片單板之玻璃板54之間有一中間膜56，且其中間膜56具有紫外線遮蔽機能。調光窗50因設置有紫外線遮蔽機能，故可減低調光板材14之液晶調光材料的液晶32因紫外線而劣化的情形。 The dimming window 50 of Fig. 5 uses the laminated glass 52 as an outdoor side glass plate. The laminated glass 52 is a well-known laminated glass having an intermediate film 56 between the glass sheets 54 of the two single sheets, and the intermediate film 56 has an ultraviolet shielding function. Since the dimming window 50 is provided with an ultraviolet shielding function, the liquid crystal 32 of the liquid crystal light adjusting material of the light control plate 14 can be degraded by ultraviolet rays.
中間膜56，具體來說，係使不含鹵素原子之苯并三唑系紫外線吸收劑等之紫外線吸收材料添加於中間膜56之材料中而使其具有紫外線遮蔽機能。另外，調光窗50亦可使用圖5之層合玻璃52來取代單板之室內側玻璃板18。 Specifically, the interlayer film 56 is obtained by adding an ultraviolet absorbing material such as a benzotriazole-based ultraviolet absorber containing no halogen atom to the material of the interlayer film 56 to have an ultraviolet shielding function. In addition, the dimming window 50 can also use the laminated glass 52 of FIG. 5 instead of the indoor side glass plate 18 of a single board.
於圖4係藉由成膜紫外線遮蔽層42來賦與調光窗 40紫外線遮蔽機能，而於圖5則係藉由使紫外線吸收材料添加於中間膜56之材料中來賦與調光窗50紫外線遮蔽機能。於本發明之實施形態中，具有紫外線遮蔽機能之調光窗並不侷限於該等。舉例來說，於製造圖1所示之室外側玻璃板16或室內側玻璃板18時，亦可藉由將氧化鈰等之紫外線遮蔽材料添加於玻璃材料中，使單板之室外側玻璃板16或室內側玻璃板18具有紫外線遮蔽機能。 In FIG. 4, the dimming window is imparted by the film forming ultraviolet shielding layer 42. 40 ultraviolet shielding function, and in Fig. 5, the ultraviolet shielding function of the dimming window 50 is imparted by adding the ultraviolet absorbing material to the material of the intermediate film 56. In the embodiment of the present invention, the dimming window having the ultraviolet shielding function is not limited to these. For example, when manufacturing the outdoor side glass plate 16 or the indoor side glass plate 18 shown in FIG. 1, the outdoor side glass plate of the veneer may be added by adding an ultraviolet shielding material such as cerium oxide to the glass material. The 16 or indoor side glass panel 18 has an ultraviolet shielding function.
〔吸熱玻璃、熱反射玻璃及隔熱玻璃〕 [heat absorbing glass, heat reflecting glass and insulating glass]
作為其他形態，可舉將室外側玻璃板16及室內側玻璃板18中之至少一玻璃板，以吸熱玻璃、熱反射玻璃或是隔熱玻璃構成之例。只要為該形態，則可抑制車輛室內及多層玻璃內之升溫。藉此，可提高室內之舒適性，並減低調光板材14之液晶32因熱而劣化的情形。 As another aspect, at least one of the outdoor side glass plate 16 and the indoor side glass plate 18 may be formed of heat absorbing glass, heat reflecting glass, or heat insulating glass. As long as it is in this form, the temperature rise in the vehicle interior and the multilayer glass can be suppressed. Thereby, the comfort in the room can be improved, and the liquid crystal 32 of the light control sheet 14 can be degraded due to heat.
熱反射玻璃則可列舉表面具有熱反射膜之玻璃板及黏貼有熱反射薄膜之玻璃板。又，於玻璃板為層合玻璃時，可藉由使紅外線吸收劑添加於中間膜之材料中而製得吸熱玻璃。 Examples of the heat reflective glass include a glass plate having a heat reflective film on the surface and a glass plate to which a heat reflective film is adhered. Further, when the glass plate is a laminated glass, the heat absorbing glass can be obtained by adding an infrared ray absorbing agent to the material of the intermediate film.
作為前述熱線反射膜，可舉具有以銀或氧化錫為主成分之層的膜，即所謂的Low-E(Low Emissivity(低輻射))膜為例。該Low-E膜係以濺鍍法等之成膜法來成膜。利用Low-E膜之紅外線的反射率，雖然愈高愈好，但通常之反射率係在40~50%左右。藉由Low-E膜可抑制車輛室內之升溫。 The heat ray reflection film may be a film having a layer containing silver or tin oxide as a main component, that is, a so-called Low-E (Low Emissivity) film. The Low-E film is formed by a film formation method such as sputtering. Although the reflectance of the infrared rays of the Low-E film is as high as possible, the reflectance is usually about 40 to 50%. The temperature rise in the vehicle interior can be suppressed by the Low-E film.
作為前述熱反射薄膜，可舉於PET等之透明薄膜之表面上形成有由氧化物層或金屬層、或是由氧化物層與 金屬層構成之熱反射膜的薄膜為例。 The heat reflective film may be formed of an oxide layer or a metal layer or an oxide layer on the surface of a transparent film such as PET. A film of a heat reflective film composed of a metal layer is exemplified.
作為前述紅外線吸收劑，則可舉ITO(In2O3-TiO2系)、ATO(ZnO-TiO2系)、硼化鑭等之無機微粒子；及花青系化合物、酞青系化合物、萘酞青(naphthalocyanine)系化合物、二硫醇金屬錯合物系化合物、二亞銨(diimmonium)系化合物、聚次甲基系化合物、酞內酯(phthalide)系化合物、萘醌系化合物、蒽醌系化合物、靛酚系化合物等之有機系色素為例。 Examples of the infrared absorbing agent include inorganic fine particles such as ITO (In 2 O 3 -TiO 2 based), ATO (ZnO-TiO 2 based), and lanthanum boride; and cyanine compounds, indigo compounds, and naphthalene Naphthalocyanine compound, dithiol metal complex compound, diimmonium compound, polymethine compound, phthalide compound, naphthoquinone compound, hydrazine An organic dye such as a compound or a phenol compound is exemplified.
〔調光窗之變形例〕 [Modification of Dimming Window]
依據圖6所示之調光窗60之主部截面圖，係利用由室外側玻璃板16、室內側玻璃板18、及中間玻璃板62構成之3片玻璃板構成多層玻璃64，且於室內側玻璃板18之對向面18A上已貼有調光板材14者。即，作為多層玻璃亦包含具有2片以上之玻璃板者。 According to the main cross-sectional view of the dimming window 60 shown in FIG. 6, the multi-layer glass 64 is formed by three glass plates composed of the outdoor side glass plate 16, the indoor side glass plate 18, and the intermediate glass plate 62, and is indoors. The dimming plate 14 is attached to the opposite surface 18A of the side glass plate 18. That is, the multilayer glass also includes a glass plate having two or more sheets.
於前述實施形態中，作為本發明之調光窗雖然是舉適用於鐵道車輛用之窗玻璃的調光窗10來作說明，但並不侷限於此。舉例來說，本發明之多層玻璃除汽車、飛機及船舶等之窗玻璃之外，亦可適用作為建築物之窗玻璃。 In the above embodiment, the dimming window of the present invention is described as being applied to the dimming window 10 of the window glass for a railway vehicle, but the present invention is not limited thereto. For example, the multi-layer glass of the present invention can be applied as a window glass for a building in addition to window glass for automobiles, airplanes, and ships.
依據本發明，藉由具有防眩機能的同時減低混濁感，可提供一種提升外觀，又具有已提升對外力之抗衡力量之調光板材的調光窗，特別是作為鐵道車輛等之窗玻璃用是有效用的。 According to the present invention, by having an anti-glare function and reducing the turbidity, it is possible to provide a dimming window for a dimming plate which has an improved appearance and a counter-strength of external force, particularly as a window glass for railway vehicles and the like. It is effective.
